使用docker搭建GitLab个人开发项目私服-编程知识

一、安装docker

1.更新系统

dnf update

# 最后出现这个标识就说明更新系统成功
Complete!

2.添加docker源

dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo

# 最后出现这个标识就说明添加成功
Adding repo from: https://download.docker.com/linux/centos/docker-ce.repo

3.安装docker，并允许卸载已经安装的软件(建议不加，避免出现卸载其他软件所需的依赖，而导致其他软件使用异常)

yum install -y docker-ce --allowerasing

# 最后出现这个标识就说明安装成功
Complete!

4.启动 Docker

systemctl start docker

5.查看 Docker 启动状态

systemctl status docker
active说明docker已经启动。

● docker.service - Docker Application Container EngineLoaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)Active: active (running) since Sun 2024-04-21 06:37:45 EDT; 51s agoDocs: https://docs.docker.comMain PID: 88635 (dockerd)Tasks: 9Memory: 34.3MCGroup: /system.slice/docker.service└─88635 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sockApr 21 06:37:45 node-05 systemd[1]: Starting Docker Application Container Engine...

6.设置 Docker 开机自启

systemctl enable docker

二、安装GitLab

1.查找GitLab

docker search gitlab

2.拉取gitlab镜像

docker pull gitlab/gitlab-ce:latest
如果查找的镜像没有自己想要的，直接使用拉取gitlab/gitlab-ce:latest这个官方最新镜像。

# 看到一下信息，说明镜像拉取成功，也可以通过docker images查看拉取的镜像，如果能看到gitlab/gitlab-ce镜像，说明拉取成功
latest: Pulling from gitlab/gitlab-ce

Status: Downloaded newer image for gitlab/gitlab-ce:latest
docker.io/gitlab/gitlab-ce:latest

3.启动gitlab

注意先使用一下命令创建挂载卷目录：mkdir -p ./software/gitlab/{logs,data,config}，这样就可以不用进入容易查看gitlab的一些目录。

docker run -d \
--hostname gitlab.orkasgb.com \
-p 8443:443 -p 8090:80 -p 8022:22 \
--restart always --name gitlab \
-v /orkasgb/software/gitlab/config:/etc/gitlab \
-v /orkasgb/software/gitlab/log:/var/log/gitlab \
-v /orkasgb/software/gitlab/data:/var/opt/gitlab \
--privileged=true gitlab/gitlab-ce \
参数解释：
-d #后台运行，全称：detach
-p 8443:443 #将容器内部端口向外映射，全称：publish
-p 8090:80 #将容器内80端口映射至宿主机8090端口，这是访问gitlab的端口，全称：publish
-p 8022:22 #将容器内22端口映射至宿主机8022端口，这是访问ssh的端口，全称：publish
–restart always #容器自启动
–name gitlab #设置容器名称为gitlab
-v /orkasgb/software/gitlab/config:/etc/gitlab #将容器/etc/gitlab目录挂载到宿主机/usr/local/gitlab/etc目录下，若宿主机内此目录不存在将会自动创建
-v /orkasgb/software/gitlab/log:/var/log/gitlab #与上面一样
-v /orkasgb/software/gitlab/data:/var/opt/gitlab #与上面一样
–privileged=true #让容器获取宿主机root权限
gitlab/gitlab-ce #镜像的名称，这里也可以写镜像ID

4.查看启动日志

docker logs gitlab

  - acme (4.1.6)
# 如果没有明显错误，说明启动正常
